The console hacking types have taken it to the PlayStation 3 and have successfully created disc image files of games. By using an install of Linux on the console, games such as Madden 07, Resistance and Genji have all been ISO dumped and released on the Internet. Being images from Blu-ray media means that we’re dealing with current file sizes between Madden’s 7.08 GB and Resistance’s 17.53 GB.
Sony said prior to the PS3 launch that Resistance would use nearly the entire 25 GB space afforded by a single-layer Blu-ray disc. Developer Insomniac said, however, that the final size of the gold master was around 16 GB. Ted Price of Insomniac writes: "As we moved into the final week of finishing up the game we made two big changes which dropped the size of the final disc to just over 16Gb – still pretty large nonetheless. What were the changes? We removed PAL movies and further improved our data compression."
There’s still a small discrepancy between the developer’s quote and the size of the image dump. The difference is due to padding files, which contains no data but is there to aid in load times. According to Mmmkay of Beyond3D forums, the file type breakdown for Resistance sees padding making up 1.9 GB, FMV 7 GB, audio 2.24 GB and game data 6.12 GB.
The console hacking community may still be a long way from cracking the PlayStation 3, but the investigation into game files is the same way that the PSP homebrew effort began.
